Xlight FTP Server 3.9.1 SEH Overwrite Buffer Overflow

Xlight FTP Server 3.9.1 contains a structured exception handler (SEH) overwrite vulnerability that allows local attackers to crash the application and overwrite SEH pointers by supplying a crafted buffer string. Attackers can inject a 428-byte payload through the program execution field in virtual server configuration to trigger a buffer overflow that corrupts the SEH chain and enables potential code execution.
